As dandelions are known to be one of the most invasive species in the world, they are not good for grass, or any plant around them. Dandelions invade any area that has grass, and its roots starts eating all the grass and plants around it to make space for it. They can also grow REALLY large, which can cause more plants to die.
Since dandelions reproduce really quickly, if they start in a backyard/small area of land, they’ll easily fill the whole place with dandelions, and kill most of the other plants, and over time can cause local extinction of a species.
Dandelions, on the map are located everywhere in North America. They’re all over the continent, and have no specific place of reproduction, as they reproduce everywhere. They are found in just about every single block in North America, however, they’re found in larger quantities in waste areas where there is a lot of garbage etc.
Dandelions are invasive species that start off by 1 plant, and spread widely over a short period of time. They have sharp leaves on their stem, sometimes with tiny hair on them and sometimes hairless. They get eaten by over 90 insect species, which makes them sometimes important for bugs in certain areas.
Dandelions don’t grow in areas with high, or low temperatures, and have certain requirements to live in an area. They can not live in areas like Africa, where the temperature is really high, and grass isn’t found, but they can live in areas like North America where they can find a lot of grass, and a fairly good condition.
How human activities contributed to the problem. Since humans move all over the planet, they carried the seeds of Dandelions all over the place. How some humans are careless, Dandelions would spread all over their backyards too!
